This volume presents research from a variety of perspectives on the enhancement of human intelligence. It is organized around five themes - enhancement via instruction; enhancement via development (over the life cycle); enhancement over time; enhancement via new constructs; and new directions in enhancement. Three key issues are addressed:
*First, although most of the scientific research on intelligence has concerned what it is, this volume attends to the consequential societal and economic issue concerns of whether it can be increased, and how.
*Second, intellectual enhancement is particularly important when targeted to minorities and the poor, groups that have typically performed relatively less well on intelligence and achievement measures. This volume reflects the education community's ongoing interest in understanding, and attempting to close, achievement or test score gaps.
*Third, most of the attention to examining intellectual enhancement, and in accounting forand closing the test-score gap, has focused on general cognitive ability. In line with the current emphasis on considering intelligence from a wider perspective, this volume includes constructs such as emotional and practical intelligence in definitions of intellectual functioning.
"Extending Intelligence: Enhancement and New Constructs" is an essential volume for researchers, students, and professionals in the fields of educational psychology, intelligence, educational measurement and assessment, and critical thinking.

Since the mid-80s several laboratories around the world have been developing techniques for the operational use of tests derived from item-generation. According to the experts, the major thrust of test development in the next decade will be the harnessing of item generation technology to the production of computer developed tests. This is expected to revolutionize the way in which tests are constructed and delivered. This book is a compilation of the papers presented at a symposium held at ETS in Princeton, attended by the world's foremost experts in item-generation theory and practice. Its goal is to present the major applications of cognitive principles in the construction of ability, aptitude, and achievement tests. It is an intellectual contribution to test development that is unique, with great potential for changing the ways tests are generated. The intended market includes professional educators and psychologists interested in test generation.

Richard Snow's research influenced many students and colleagues, both directly through his findings and indirectly by inspiring others to carry on the work. A cross-section of his influence is represented in this special issue. The articles present several themes in his work, including the importance of multivariate considerations of individual differences, adapting instruction to individual learners, a process understanding of aptitude, and an enlarged role for spatial ability. Each paper picks up one of the themes identified--trait complexes, ATIs, process analyses, and spatial ability--and has a strong quantitative, empirical foundation but is nested within appropriately complex theoretical frameworks.
